Watir Webdriver(0.9.1)不再打开Firefox实例

Question

使用Watir Webdriver v0.9.1 for rails(以及Selenium Webdriver 2.53.1)时,Firefox正在打开时

  browser = Watir::Browser.new :firefox

被称为.然而,现在它失败了

      test/integration/like_fanpage_task_test.rb:40:in `block (2 levels) in <class:LikeFanpageTaskTest>'

它似乎随机地这样做,因为我没有从其工作形式更改代码,并且该行是第一行调用.我有Firefox 37.0.2,之前有效.我已经尝试重新启动计算机,杀死与ruby和Firefox相关的进程并重新启动它们,并重新安装Firefox但无济于事.

Mozilla推出了一个新的webdriver,由于firefox 47中的一个bug,只有新的webdriver适用于firefox.但是我会建议永久切换到新的webdriver,因为firefox 48将完全删除支持.

您可以使用以下命令在ruby中使用新的webdriver:

driver = Selenium::WebDriver.for :firefox, marionette: true

但我不知道这是否会使你能够在watir中使用它.

至于我可以告诉marionette(新驱动程序)支持还没有在watir中完成(我可能是错的),我看到这个 pull请求正在处理它但它没有完成或合并.

它看起来像你可以这样做:

browser = Watir::Browser.new :marionette

当watir项目完成集成新驱动程序时.
